This will be the first presidential primary where I'm somewhat torn on who to vote for. (Dole was my first presidential candidate to cast a vote for back in 96...things were bad, then. heh heh)
Rudy has had my support because he has proven leadership, and he has been one of the few not to come out criticizing President Bush's handling of Iraq. He also fully understands the severity of this Sunni movement. However, he is more liberal on social issues than I am. That being said, I'm more worried about a nuke going off in a major city than Rudy's support of precedent regarding the SCOTUS' asinine decision in Roe. v Wade. Thompson, in my opinion, will show dedication to fighting these Islamic nutjobs, and will fill the conservative void that Rudy was incapable of doing.
I can very much see a Bush/Reagan type ticket coming together with Thompson picking Rudy to be his VP.
